Ventilation duct cleaning in City of Westminster, done properly
We always start by inspecting. We look inside the ductwork at set points and record what’s there, and cleaning is recommended where the inspection shows it’s due. That way the work matches the real condition. The work covers hospitals and care homes, offices and schools and general extract ductwork, and people most often call us about ducts that need a clean before handover and grilles and diffusers streaked with dirt.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in City of Westminster, dust and debris build up in the units and ductwork over time.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Signs you need ventilation duct cleaning in City of Westminster
Filters never catch everything, so fine dust settles in supply ductwork over the years. Extract ducts collect whatever the rooms give off: dust, fibres and lint.
What we’re most often called out for:
- Musty smells from the ventilation
- Ductwork never cleaned since it was installed
- Systems missing access panels
- Toilet and washroom extracts full of fluff
Wherever a school like St Vincent's Catholic Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from a single shift for a small office to a planned programme of nights for a large building, and we clear up before we go. If your building in City of Westminster has sign-in rules, permits or key holders, mention them when you book.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- Before photos are taken and the ducts cleaned section by section.

Getting ready for the visit

Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Part by part
Schools and colleges
Schools and colleges are easiest to clean during the holidays, with nobody in the classrooms.
Extract ductwork
Washroom extracts handle damp air, so the dust tends to cling. We clean them and note any damp or corrosion.
What ventilation duct cleaning cannot fix
To be straight with you, there are a few things this work won’t fix:
- Damp or mould problems coming from the building fabric
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- Building management settings that run the plant
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer.

FAQs for City of Westminster
What do you need to know about parking in City of Westminster?
A loading bay, a visitor permit or off-street space near the site in City of Westminster makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Can you come to City of Westminster after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
When should our ventilation next be cleaned?
There’s no single interval; under TR19® Air, inspection decides. We suggest a next inspection date after every visit.
Does the law say we must follow TR19?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do we need to close while you work?
Not normally. The area we’re working in has to be out of use while we’re there, so the visit goes in a quiet slot.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Why deal with it now?
Facilities teams are regularly asked to show evidence of ventilation hygiene. Having a recent certificate and photo report for a building in City of Westminster answers the question. Every month a London system goes without attention adds to what has to be done later.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.

Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Get leaks near ductwork fixed quickly
- Flag any dust coming out of the vents
- Switch the ventilation off or cover grilles during dusty building work
- Wipe grilles and diffusers during routine cleaning
A TR19® certificate and photo report follow every clean. Keep them in the maintenance log, with the date, location and technician recorded.
Deal with condensation and leaks near ducts promptly, as wet dust is much harder to clean.
